remote desktop error 「CredSSP 加密預示修復」錯誤

「CredSSP 加密預示修復」錯誤

最常見的案例是，用戶端已安裝 CredSSP 更新，而 加密預示修復 措施設定會不允許使用遠端桌面協定連線至未安裝 CredSSP 更新的伺服器。

如果需要替代的解決方案，請依照下列步驟執行：

1. 在用戶端上安裝 CredSSP 更新，執行 gpedit.msc，然後在導航窗格中瀏覽至 電腦設定 > 系統管理範本系統>認證委派  
2. 將加密預示修復 變更為啟用，然後將保護層級變更為 易受攻擊。

Unlock root account in HP-UX

From
How to unlock locked root account in HP-UX

By default HP-UX disables the root account if there is repeated number of failed (bad password) attempts. If you root account has been disabled because of bad password there are two options you two ways you can unlock the account without rebooting the server.

1.If you have sudo installed and your account is setup with root privileges then you can login as sudo su and then you can unlock the account using modprpw

$/usr/local/bin/sudo su –

##/usr/lbin/modprpw –l –k root


2.If you don't have sudo setup then other way out is to check on GSP console if you already have root logged in then you can re-enable root account from GSP console

Solaris Explorer

當你Solaris OS發生問題要怎麼辦
首先，你必須將系統的狀況回報給維護廠商

1. 執行 Explorer 程式:
# cd /opt/SUNWexplo/bin
# ./explorer

如果要針對Storage問題，執行指令如下
# ./explorer -w default,storage,fru

當程式執行完畢你會看到
explorer: Explorer finished 的訊息

2. 當程式執行完後,
# cd /opt/SUNWexplo/output
# ls
explorer.XX-2007.12.16.07.43.XXXX
explorer.XXXXXXXXX-2007.12.16.07.43.tar.gz
把 explorer*.tar.gz 寄出給維護廠商

Sybase's Login

Sometimes, we would like to know where a sybase's user come from? (e.g. IP)
1.) Find out the login's suid by using sp_displaylogin
1> sp_displaylogin person1
2> go
Suid: 2608
Loginame: person1
Fullname:
Default Database: mydb
Default Language:
Auto Login Script:
Configured Authorization:
Locked: NO
Date of Last Password Change: Nov 27 2007 11:03AM
Password expiration interval: 0
Password expired: NO
Minimum password length: 6
Maximum failed logins: 0
Current failed login attempts:
(return status = 0)
2.)Then select from sysprocesses by using the "suid"
1> select * from sysprocesses where suid=2608
2> go
spid kpid enginenum status suid hostname
program_name hostprocess cmd cpu physical_io
memusage blocked dbid uid gid

Logging for executed commands

Solaris作業系統可以通過設置日 誌檔可以對每個用戶的每一條命令進行紀錄，這一功能默認是不開放的，為了打開它，需要執行/usr/lib/acct目錄下的accton檔，格式如下 /usr/lib/acct/accton /var/adm/pacct，在sun的手冊上，只有這一種用法，但這樣做的缺點是明顯的，大多數有經驗的入侵者一定不會放過/var/adm和 /var/log這兩個目錄的，如果它們看到有pacct這個東西，不刪才怪。針對這種情況其實有個很好的解決辦法，執行 /usr/lib/acct/accton 後面跟一個別的目錄和檔即可，如/usr/lib/acct/accton /yiming/log/commandlog，這樣入侵者不會在/var/adm/下看到pacct，入侵者也許會刪掉message，syslog等 日誌，但他並不知道實際上他所有的操作都被記錄在案，管理員事後只要把commandlog這個檔拷貝到/var/adm下，改為pacct ，同時執行讀取命令lastcomm，就一切盡在掌握啦。如lastcomm hack，可得到下面的輸出結果：

Sybase "sa" Passwords Recovery

1. kill the sybase server

2. edit $SYBASE/ASE-12_5/install/RUN_ file

3. add "-psa" :
#!/bin/sh
#
# ASE page size (KB): 2k # Master device path: /home/sybase/data/master.dat
# Error log path: /home/sybase/ASE-12_5/install/SUN1.log
# Configuration file path: /home/sybase/ASE-12_5/SUN1.cfg
# Directory for shared memory files: /home/sybase/ASE-12_5
# Adaptive Server name: SUN1
# /home/sybase/ASE-12_5/bin/dataserver \
-d/home/sybase/data/master.dat \
-e/home/sybase/ASE-12_5/install/SUN1.log \
-c/home/sybase/ASE-12_5/spxh2_train.cfg \
-M/home/sybase/ASE-12_5 -psa \
-sSUN1 \

4. start the sybase server
./startserver -f RUN_

for example:
.....
00:00000:00001:2001/05/26 18:29:21.39 server 'bin_iso_1' (ID = 50)
00:00000:00001:2001/05/26 18:29:21.39 server on top of default character set:
00:00000:00001:2001/05/26 18:29:21.39 server 'iso_1' (ID = 1).
00:00000:00001:2001/05/26 18:29:21.39 server Loaded default Unilib conversion handle.

New SSO password for sa:tmfyrkdwpibung <-- find this line
.....

5. login sybase: isql -S -Usa -Ptmfyrkdwpibung

6. change sa password: sp_password tmfyrkdwpibung,newpasswd

7. shutdown sybase

8. fallback RUN_ file

9. start sybase again

OK now! =)

Solaris "root password" Recovery

今天從 http://solaris.tophk.net/forum/viewtopic.php?t=117 & http://wiki.gceclub.sun.com.cn/index.php/Opensolaris_chinese_faq 看到的 =)

較近的 solaris 10u1 & 11 (是用 grub 開機的):

1. start from "fail safe" mode
2. 系统會問你是否 mount "/" 分區到 /a 上，選 yes
3. 编辑 "/a/etc/shadow"，delete "root" 的passwords，save & reboot

Solaris 9 & 10  (不是用 grub 開機的):

1. 用 disk 1 boot 機
    [X86]： BIOS set cdrom boot 機
    [Sparc]：press "Stop+a" (SUN keyboard) or "ctrl+break" (PC keyboard) 進入到OBP & enter：
                   ok boot cdrom -s

2. 然后，mount "/" 分區，edit "shadow"：
    mount /dev/dsk/c0t0d0s0 /mnt (assume 你 harddisk 上的 "/" 區是 "/dev/dsk/c0t0d0s0"
    vi /mnt/etc/shadow

另一方法

1.將安裝Solaris 10光碟片第一片放進來，並開機
2.選擇安裝方式，直接按【Enter】繼續
3.會開始拷貝系統安裝所需要的資料，大約等了5分鐘，會進入選擇語言畫面
4.利用滑鼠按下右鍵，選擇【Windows\New】，會出現一個新的視窗
5.輸入 mount /dev/dsk/c0d0s0 /mnt指令，會將根目錄Mount在mnt目錄下
6.輸入chmod 600 /mnt/etc/shadow
7.編輯/mnt/etc/shadow檔案，將root這一行的第二個密碼欄位Del掉，使其 保留空白
8.儲存結束，並重新開機，記得光碟片要拿起來，就不用輸入密碼，可以直接 登入

ipcalc on windows

linux 有個好好用的計 ip 工具 -- ipcalc
想在 windows 用都可以的, here is:

1. download ipcalc.pl from http://jodies.de/ipcalc
2. download activeperl from http://www.activeperl.com
3. install activeperl just click "Next" and "Finish" XD
4. move the ipcalc.pl file to c:\perl
5. open the command prompt
6. cd c:\perl
7. pl2bat ipcalc.pl
8. thats it!

Windows XP auto-reboot problem

試過好多次遇到 Windows XP 不停 reboot 的問題, 無論正常或 safe mode 都一樣! 一向的解決方法都是 re-install (不影响 data) Window 和 所有的 program, 實在浪費時間...

 

今日無意中在網上發現到一個類似的 case 和解決方法 =) 有機會就 check 下 work 唔 work???

 

方法大槪是要令到一個叫 "cnsminkp.sys" 的 file 不會在開機時就 run, 咁就 ok 了 =)

 

solutions:

1. find and delete cnsminkp.sys (default path 是 C:\Windows\System32\cnsminkp.sys)

     如果有裝2個以上的 OS, 就好簡單啦 (當然要 read 到 WinXP 的安裝目錄);

     如果得一個 OS 咁就入去 "恢復控制台" 啦

 

2. Disable CnsMin

    同樣可以入去 "恢復控制台", 輸入 " Disable CnsMin" 的 command

BIOS有密碼點算???

當你整機時發現個 BIOS 有 set 到密碼，你是否又諗住拆機 clear CMOS 呢???

GREAT NEWS! 這個網頁提供了一些 BIOS 制造商的 BLACKDOOR 密碼 How to Bypass BIOS Passwords

e.g.
Award BIOS backdoor passwords:

ALFAROME		BIOSTAR		KDD		ZAAADA
ALLy		CONCAT		Lkwpeter		ZBAAACA
aLLy		CONDO		LKWPETER		ZJAAADC
aLLY		Condo		PINT		01322222
ALLY		d8on		pint		589589
aPAf		djonet		SER		589721
_award		HLT		SKY_FOX		595595
AWARD_SW		J64		SYXZ		598598
AWARD?SW		J256		syxz
AWARD SW		J262		shift + syxz
AWARD PW		j332		TTPTHA
AWKWARD		j322

FreeBSD r6.1 安裝 notes (1)

因我用 winxp boot 機，所以先把 freebsd cd1 中的 boot/boot1 copy 到 C:\fbsdboot\boot1
修改 boot.ini︰加入 C:\fbsdboot\boot1="freebsd 6.1"
(p.s. 跟著這裏教的 =D)

用 disk genius 清空一個 10G partition，把 freebsd 安裝下去!直接用 auto 分了區 (比較 lazy 嘛，加上我肯定 freebsd 的 FDisk 比 RH Linux 的差 XD)， 再 set 好一堆必要的東東....
因我只有 cd1，所以連 cvsup 都要上 ftp 取來裝。終於都安裝完 freebsd.....一個超簡陋的 x-windows 模式。

真正的 post-install 才開始 (救命!)︰
# cp /usr/share/examples/cvsup/ports-supfile /usr/local/etc (有點多餘的 =P)
# cvsup -h cvsup2.freebsd.org /usr/local/etc/ports-supfile.....超耐 =(

安裝 icewm (windows manager)、firefox、openoffice、icewmcp等....又花去了一段時間設定

總算有個似像的 OS (一點 server 功能都沒有 XD)

無用的 Partition Magic & 有用的 Disk Genius

今天本來一嘗 install FreeBSD 的滋味，但竟然浪費了很多時間的在 Harddisk 的分割上....唉!

我的電腦本來已經有一個 winxp 和一個 win2003 =D 但只有一個 primary ， so 我要 create 多一個 primary。奇怪的事開始發生了....一心想用win2003 的 disk manager，boot 唔到入 win2003 ??? 算 X D ! 我發現原來 winxp 都有 disk manager，但原來係癈的......

好就用 partition magic 吧，點知它竟然認不出我一些 partition ，只認到一塊 winxp 的 fat32 (primary)、一塊未format的(留給 FreeBSD 用)、一塊吉的 ntfs和其它一大塊在extend 中的 unallocated 的空間。其實在一大塊中還有幾個 fat32 和 我的 win2003....迷???

我就沒理會那個「迷」，直接把那塊未 format 的空間轉為第二個 primary。當我按下 apply 後，麻煩就開始了.....我在 winxp 中見不到所有其它存於 extend 中的 drive， 包括我的 win2003。

我在 winxp 中只看見一個 c:\、一個留給 FreeBSD 用的 drive 和 那個吉的 ntfs。bullshit 我實在太相信 partition magic，我以為它只會做我叫它做的事 (把其中一塊 extent partition 轉為 primary )，竟然還把一大塊它認不到的 extent partition 消失掉。我所有的其它 data 都無了嗎??? 不會吧......

又要靠 google 了，好彩偉大的祖國人民發明了一個 program ==> Disk Genius。可以簡單地 (其實是自動地 =D)重新 setup 好 partition table。你只需要一張 dos 的 boot 機碟 (我都花了一點時間，才找到一張 N 年前的 win95 bootdisk =P)，因為 disk genius 只會在純 dos 的還境下工作。

運行 disk genius 後，它有一個重新設置 partition table 的功能可以自動搜尋 harddisk 中存在的各種不同格式的 partition 然後重新寫入 partition table 中。GOOD~~太偉大啦.......

ps. disk genius is free...and it also includes many functions for disk management =D

好用的 rss reader

用 RSS 去睇 BLOG 真係好方便, but 無得留 comments =P

SHARPREADER 一個好簡單易用的 Reader, 不過一樣要裝 M$ 的 .NET Framework (麻煩的 windows >( )
http://www.sharpreader.net/

YAHOO Widgets

Widgets 應該是由 Mac 機提出的吧???

anyway 如果你是 windows xp 的用者, 就用 yahoo 的 widgets tool 吧??? 你更加可以自己開發及將它分享出來啊! =D

Lotus Notes 6

之前從未試過在家中的電腦安裝 Lotus Notes，一向都覺得 Outlook Express 都已經很夠用了 =D印象中 Notes 應該和 M$ 記的 OUTOOK 差不多吧??? 不過既然從未深入接觸過......(強烈好奇心下)一於裝裝它吧=D

一開始就出事了 - how/where to get it ??? 我記得 notes 是 free 的，domino server 就要錢買 (應該無記錯吧???) ...好自然地 google 一下吧! oh my god! IBM 買起了 LOTUS 吧??? 唉.....我完全不知道 =( 以為好容易就 download 到 notes 7，but 又要 register (最討厭的 step)，最後重要不能成功 reg 到 有無搞錯 =[] $%#!@!#@

再 google x 1 x 2 x 3 x 4.......GREAT 終於比我找到了 (原來一點不易??? 奇怪...不是 free 的嗎)雖然只是 R6 但都不錯，加上我本身只是想裝 notes 5 (因曾經接觸過 =D)
安裝過程一如所料般 easy，不消幾分鐘便搞掂了 yeah! notes 6 的介面比 notes 5 漂亮很多，不過我並不喜歡因為華麗的介面而要消耗 resource 的 software，好彩 notes 6 都不算太慢 (當然 R5 會更快)

我沒有 domino server，所以只好用來做 pop/smtp 等 internet services .....當所有 setting 都無難度地完成後，打開 inbox 之際.... 空白一片，OE 中的 SEND & RECEIVE 同 NETSCAPE 中的 GET MESSAGE 在 NOTES 中是叫什麽的呢??? 我發現自己真的是退步了很多，一個咁簡單的 software 都要 google 幫手...唉! 原來 notes 中是有一個叫 REPLICATION 的功能的 =P。
一於用 NOTES 取代我的 PALM DESKTOP 吧 =D

復原 MySQL root 密碼

忘記了 MySQL 的 root 密碼，可以用以下方法重新設定：

1. 關閉 MySQL 伺服器。

2. 用以下指令啟動 MySQL，以跳過檢查權限的資料表
mysqld_safe –skip-grant-tables &<

3. 現在己經可以用空密碼進入 MySQL
mysql -u root

4. 進入 MySQL 後執行以下指令更改 mysql root 密碼：
mysql> update mysql.user set password=PASSWORD(”new_password”) where User=’root’;
mysql> flush privileges;
mysql> quit

5. 最後只需重新啟動 MySQL，便可以用新設定的密碼進入了。
